如何跳過或忽略python裝飾器

Question

有一個由裝飾器包裝的函數，該裝飾器將函數的輸出作爲HTML返回。我想在沒有裝飾器的HTML包裝的情況下調用該函數。這甚至有可能嗎？

例子：

class a: 
    @HTMLwrapper 
    def returnStuff(input): 
     return awesome_dict 

    def callStuff(): 
     # here I want to call returnStuff without the @HTMLwrapper, 
     # i just want the awesome dict. 

Answer 1

class a: 
    @HTMLwrapper 
    def return_stuff_as_html(self, input): 
     return self.return_stuff(input) 
    def return_stuff(self, input): 
     return awesome_dict 

我做同樣的事情在等待響應，它爲我工作得很好，但我仍想知道是否有更好的方法： ） - olofom

由於在python函數和方法中是對象，並且由於裝飾器返回可調用對象，所以可以在裝飾方法上指定一個屬性指向原始方法od，但是像my_object_instance.decorated_method.original_method（）這樣的調用會更加醜陋，並且不夠明確。

The Zen of Python, by Tim Peters 

Beautiful is better than ugly. 
Explicit is better than implicit. 
Simple is better than complex. 
Complex is better than complicated. 
Flat is better than nested. 
Sparse is better than dense. 
Readability counts. 
Special cases aren't special enough to break the rules. 
Although practicality beats purity. 
Errors should never pass silently. 
Unless explicitly silenced. 
In the face of ambiguity, refuse the temptation to guess. 
There should be one-- and preferably only one --obvious way to do it. 
Although that way may not be obvious at first unless you're Dutch. 
Now is better than never. 
Although never is often better than *right* now. 
If the implementation is hard to explain, it's a bad idea. 
If the implementation is easy to explain, it may be a good idea. 
Namespaces are one honking great idea -- let's do more of those! 

Answer 2

肯定的：

class Example(object): 
    def _implementation(self): 
     return something_awesome() 

    returnStuff = HTMLwrapper(_implementation) 

    def callStuff(self): 
     do_something_with(self._implementation())

__author__ = 'Jakob' 

class OptionalDecoratorDecorator(object): 
    def __init__(self, decorator): 
     self.deco = decorator 

    def __call__(self, func): 
     self.deco = self.deco(func) 
     self.func = func 
     def wrapped(*args, **kwargs): 
      if kwargs.get("no_deco") is True: 
       return self.func() 
      else: 
       return self.deco() 
     return wrapped 

def spammer(func): 
    def wrapped(): 
     print "spam" 
     return func() 
    return wrapped 

@OptionalDecoratorDecorator(spammer) 
def test(): 
    print "foo" 

test() 
print "***" 
test(no_deco=True)
